Title: Storing Optical Fibre
IPC: B65H54/76
Filed: 1981-04-29
Abstract: Apparatus for terminating an optical fibre includes a storage box for storing a surplus length of optical fibre left at the termination point for subsequent use on reterminations. The box may be a flat pack 1,2 including a disc or drum member 3 around which an inserted optical fibre passes between entering the box at aperture 6 and leaving it through aperture 5 so that the optical fibre is prevented from adopting an unacceptably small radius of curvature. Alternatively the box may be drum shaped with an internal radius of not less than the predetermined acceptable radius of curvature for loops of optical fibre, the entry 15 and exit 19 apertures of the box being arranged such that the inherent tendency of optical fibres to straighten causes a surplus length of fibre left in the drum to adopt the widest radius of curvature that the drum will permit and be constrained by the periphery of the box. The box may be divided into two portions so that a length of optical fibre may be stored in each portion, and at least part of the box may be transparent. <IMAGE>

Patent GB-2097412-A (GB)
Title: Improvements in unsaturated halogenated polyester resins
IPC: C08F299/04
Filed: 1982-03-22
Abstract: An unsaturated halogenated polyester resin composition for open lay-up moulding contains styrene as an agent for cross-linking during curing and additionally contains 0.1 to 5% by weight, based on the total weight of the composition, of at least one C18-40  alpha -olefine compound which is theoretically capable of taking part in the cross-linking reaction. The  alpha -olefine compound itself may alone serve to provide a marked restriction in styrene evaporation from the composition. However, more usually this is not the case but the olefine does allow incorporation into the composition of a waxy compound in an amount sufficiently large to achieve the desired styrene evaporation restriction without deterioration of the adhesion properties of the composition during lay-up.

Patent GB-2113072-A (GB)
Title: Shoe soles
Inventor: AHN BYONG-RYOL
IPC: A43B7/00
Filed: 1983-01-05
Abstract: A flexible sole for use with hiking, running, or walking shoes comprises flexible protrusions 3 extending from a support portion in a direction inclined toward the rear of the shoe. As the shoe is pressed against the ground under the weight of the user, the inclined protrusions flex elastically. As the protrusions flex along their length, the bottom surface of each protrusion in contact with the ground remains fixed relative to the ground due to frictional forces. The protrusions flex by forming a smaller angle with the bottom surface 1 of the support portion. The result is that the support portion of the sole and the shoe attached to the sole move forward an additional distance relative to the point of contact between the protrusions and the ground. This enables the user to travel an increased distance with each step. <IMAGE>

Title: Attaching elevator buckets to endless belts
Inventor: HISCOCK ROGER FREDERICK
IPC: F16B39/28
Filed: 1984-09-12
Abstract: An elevator bucket is attached to an endless belt by means of a thin oval plate 1 having a circular countersunk portion 3 in one face, projections 5,6,7,8 extending from the other face, and a central hole 4 to receive the bolt of a nut and bolt assembly. The projections 5,6,7,8 are cusp-shaped, with the open faces of the projections lying on lines extending radially of the bolt hole 4 and facing in the same direction as the hand of the bolt thread. The projections 5,6,7,8 are punched out of the plate thereby providing indentations in the countersunk portion 3, which receive corresponding projections formed on the underside of the bolt head. Thus the projections 5,6,7,8 penetrate the endless belt so preventing rotation of the plate 1 when the nut and bolt assembly is tightened down. <IMAGE>
